What are the benefits of using loops in programming? Using the lecture and internet, research examples of loops in python and describe their functions. What is an example of a loop you might see in the real world?
In programming, the use of loops allows a programmer to simplify repetitious tasks with a process that will repeat itself over a series of passed values whether it is form a user passed parameter or a store set of data (for example, pulling a set of data form a database and “looping” through it to perform a series of checks).
The loop function in Python is called using the “for” statement where it will repeat a series of event in a sequence.
The syntax in Python will be: for {element_to_repeat} in {sequence}: Do something here

An example of this could be to output a user’s name on screen in a line break format such as: userName = ‘Paul’ for letter in UserName: print ‘Letter – ‘, letter print ‘That spells ‘, userName

The use of loops in a real world example could be to validate if a series of values falls into a specific range. This may include something such as determining if a set of salaries was higher or lower than a national average. In a previous example, we wrote code that would determine how many years remained in a set of employees until they retired. In my work, I often use loops to run through a set of product serial numbers and determine if each one is in a manufacturer’s warranty or not prior to us shipping...

Pt1420 Week 3 Programming Assignment

...This week’s programming assignment on how to sort fruits and arrange them in alphabetical order was not easy to do. It took me to do many examples and readings to understand the code in looping structure that is for loop, in the while loop. I have to run module several times, back and forth and carefully observe and do many examples to be able to arrange all the fruit in alphabetical order. What I have learnt so far programming is that, no matter what you code if you do not give the right codes at the right place, you will not get results. Also I learnt something on the concept of a tuple which In mathematics, a tuple is an ordered list of elements. Related to this is an n-tuple, which in set theory is a collection (sequence) of "n" elements....

...Introduction 2 The Python Programming Language 2 History of Python 2 Features 4 Advantages and Disadvantages 5 Python vs. C 5 Summary 11 Bibliography 12 Introduction After comparing several programming languages, I have found many books and websites expressing how fast and efficient Python is. Further, many research papers describe the advantages of adding Python to computer sciences classes. For this reason I decided to study this language and compare it to one that I am familiar with, like the C language. This paper contains the history of Python, from its creation until now. It shows the features that make Python so popular, and the differences between Python and other languages. Most importantly, it explains the four pillars that are the foundation of the Python programming language, which are to provide quality, increase productivity, portability, and integration. Through this paper illustrate the advantages and disadvantages of Python, by showing that, although an interpretative language such as Python will never be as fast as a compiled language like C, it will be more efficient and useful in a variety of cases. The Python Programming Language History of Python Python (Software, 2011) is a relatively recent, object-oriented, interpreted scripting language created by Guido van Rossum at Stichting Mathematisch Centrum (CVI) in the Netherlands. According to Mark Pilgrim, Python is a successor of the ABC language......

...Lab 7: Functions This lab accompanies Chapter 6 of Starting Out with Programming Logic & Design. Name: ___________________________ Lab 7.1 – Functions and Pseudocode Critical Review You have been coding with modules in pseudocode and functions when using Python. You modules in pseudocode can be made into functions by returning a value. A function is a special type of module that returns a value back to the part of the program that called it. Most programming languages provide a library of prewritten functions that perform commonly needed tasks. Library functions are built into the programming language and you can call them as needed. They are commonly performed tasks. Help Video: View the tutorial video titled, "lab7-1.wmv" to assist you in completing this lab assignment. Writing Your Own Function that Returns an Integer Step 1: A function contains three parts: a header, a body, and a return statement. The first is a function header which specifies the data type of the value that is to be returned, the name of the function, and any parameter variables used by the function to accept arguments. The body is comprised of one or more statements that are executed when the function is called. In the following space, complete the following: (Reference: Writing Your Own Functions, page 225). a. Write a function with the header named addTen. b. The function will accept an Integer variable named number. c. The function body will...

After all studies where carried out, I came to a conclusion that one programing language can belong to more than one paradigm C++ C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. Some people say that C++ is a middle language because it has the features of high level and low-level language. As one of the most popular programming languages in the world, C++ is widely used in the software industry. C++ is also used for hardware design to analyze structure. Some of its application domains include systems software, application software, device drivers, embedded software, high-performance server and client applications, and entertainment software such as video games.

...Unit 1 Research Assignment 1: Exploring Programming Languages Computers don't do anything without someone telling them what to do, much like the average teenager. To make the computer do something useful, you must give it instructions in either of the following two ways: * Write a program that tells a computer what to do, step by step, much as you write out a recipe. * Buy a program that someone else has already written that tells the computer what to do. Ultimately, to get a computer to do something useful, you (or somebody else) must write a program. A program does nothing more than tell the computer how to accept some type of input, manipulate that input, and spit it back out again in some form that humans find useful. Table 1 lists some common types of programs, the types of input that they accept, and the output that they produce. Essentially, a program tells the computer how to solve a specific problem. Because the world is full of problems, the number and variety of programs that people can write for computers is practically endless. But to tell a computer how to solve one big problem, you usually must tell the computer how to solve a bunch of little problems that make up the bigger problem. If you want to make your own video game, for example, you need to solve some of the following problems: * Determine how far to move a cartoon figure (such as a car, a spaceship, or a man) on-screen as the user moves a joystick. * Detect whether the cartoon......

Software can be classified into two broad types System software and application software. Command line, a location on your computer screen at which you type text entries to communicate with the computer's operating system. The major difference between the two main programming styles in use today is programmer's focus during the earliest planning stages of a project. Graphical user interface(GUI) allows users to interact with a program in a graphical environment. The process of walking through a program's logic on paper before you actually write the program is called desk-checking.  Processing data items may involve organizing or sorting them,checking them for accuracy, or performing calculations with them. Every programming language has rules governing its word usage and punctuation. Using Pseudocode involves writing down all the steps you will use in a program.

...define a compiler-compiler or compiler generator as a tool which creates a parser, interpreter, or compiler from some form of formal description of a language and machine. The earliest and still most common form of compiler-compiler is a parser generator, whose input is a grammar (usually in BNF) of a programming language, and whose generated output is the source code of a parser often used as a component of a compiler. Similarly, code generator-generators (such as J Burg) exist, but such tools have not yet reached maturity. The ideal compiler-compiler takes a description of a programming language and a target instruction set architecture, and automatically generates a usable compiler from them. In practice, the state of the art has yet to reach this degree of sophistication and most compiler generators are not capable of handling semantic or target architecture information. History The first compiler-compiler to use that name was written by Tony Brooker in 1960 and was used to create compilers for the Atlas computer at the University of Manchester, including the Atlas Auto code compiler. However it was rather different from modern compiler-compilers, and today would probably be described as being somewhere between a highly customizable generic compiler and an extensible-syntax language. The name 'compiler-compiler' was far more appropriate for Brooker's system than it is for most modern compiler-compilers, which are more......

Abstract Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for rapid application development, as well as for use as a scripting or glue language to connect existing components together. Python’s simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed. This reference manual describes the syntax and “core semantics” of the language. It is terse, but attempts to be exact and complete. The semantics of non-essential built-in object types and of the built-in functions and modules are described in the......
